This article uses a global model to analyse empirically how the personal and professional development of educators (personal mastery) facilitates the creation of a series of basic shared values (shared vision) and of team learning by the members of the educational centre, these inter-related strategic factors favouring, in turn, educational organizational learning and subsequent improvement in organizational performance. Likewise, verification is made of different learning barriers that hinder the acquisition, dissemination and sharing of knowledge by blocking shared vision and team learning. Using a national survey in educational centres in Spain, we found that these hypotheses are verified and that organizational learning plays a key role in the generation of organizational performance.
